In this study has suggested a main hypothesis (investigating the impact of relationship marketing on improvement of company performance) and six subordinate hypotheses (investigating the impact of each of variables such as cost-centered business model design, novelty-centered business model design, cost-centered business model design in late stages of organisational life cycle, novelty-centered business model design in early stages of organisational life cycle, cost-centered business model design in early stages of organisational life cycle regarding relationship-specific investments, novelty-centered business model design in early stages of organisational life cycle regarding relationship-specific investments separately on company's performance).Based on study findings, first, second and forth hypotheses were supported. Results also showed that first subordinate hypothesis (cost-centered business model design has a significant impact on company performance) with path coefficient of 0.60 has the most impact and second subordinate hypothesis (novelty-centered business model design has significant impact on company performance) with the path coefficient of 0.29 has the least impact on company performance.
